Q 1 - You are designing an application in which a section of the main page will be populated by content from a third-party provider. You do not have control over the responsiveness of the client or how much information will be returned with each request. The call is to a Restful service and will return the information formatted in Extensible Markup Language (XML). What is the best way to implement this application?

A - Design a model that handles the data call to populate the model. Create a partial view containing only this display area and put an asynchronous service call that returns this model in the partial view controller.

B - Put a synchronous service call into the main page controller.

C - Create a partial view containing only this display area and put a synchronous service call in the partial view controller.

D - Create a partial view containing only this display area and put an asynchronous service call in the partial view controller.

E - A and D both

F - All of the above

Q 2 - What is the first request sent to start HTTP polling?

A - HTTP DELETE

B - HTTP GET

Q 3 - Your team is building an application and you are reviewing the functional specifications. Your team must include a stockticker in the UI that displays the companys stock price every 15 minutes, and include the capability to do partial saves of base objects as users step through a data entry wizard. You want to use the same approach for both requirements to make it easier to add functionality and maintain it going forward. What approach should you use?

A - Use JavaScript to refresh the page every 15 minutes and to manage whether wizard buttons are enabled or disabled.

B - Use AJAX to make asynchronous calls to the server on a timer for the stock price and to automatically save the base objects as the user navigates through the wizard.

C - Use jQuery to refresh the page every 15 minutes and to manage whether wizard buttons are enabled or disabled.

D - Use data validation annotations on the model to ensure that the stock price is validated every 15 minutes and that the client saves the base object information after every wizard step.

E - C and A both

F - All of the above

Q 4 - You are modifying an ASP.NET MVC web application and you have created a new master layout page named _Layout.WindowsPhone.cshtml. You want to use that layout in a new view. Which code segment do you use?

A - Use the Authorize attribute before the RequireHttps filter.

B - Use the RequireHttps attribute before the Authorize filter.

C - Use a custom action filter that combines the check for HTTPS and the check for authentication into a single filter.

D - Use Authorize alone; you do not need to use RequireHttps separately if you already have Authorize, because using Authorize implies the use of HTTPS.

E - C and D both

F - All of the above

Q 6 - You work for a financial services company that deals with many small brokers. Your executives want to be able to run a report that details all the actions taken by the brokers on the site as a form of auditing and protection. Neither the application nor system currently stores this kind of information. Which of the following are viable solutions? (Choose all that apply.)

A - Create a globally applied custom action filter that implements the OnActionExecuting method. Have it store the user, the URL, and the forms collection.

B - Create a globally applied custom action filter that implements the OnActionExecuting method. Have it store the user, the URL, and the forms collection.

C - Create a globally applied custom action filter that implements the OnActionExecuted method. Set the AllowMultiple parameter to false in the filter. Have it store the user, the URL, and the forms collection.

D - Override the AuthorizeAttribute and have it store the user, the URL, and the forms collection.

E - A and C both

F - All of the above

Q 7 - Your ASP.NET MVC web application has just been released to a group of pilot users. The users are reporting periods of extreme performance degradation. You did not encounter performance issues during development or the quality assurance phase. What can you do in your development environment to understand what is occurring in the production environment?

A - Create a set of unit tests that repeatedly test certain parts of the application. Run them continuously over a period of time to ensure that the application works as expected.

B - Create a set of web tests that exercise the application. Set a run load of 50 percent of your pilot users and run them in a constant load testing process to validate the application's behavior.

C - Create a set of web tests that exercise the application. Using a step approach, start with a minimal number of users and increase to the total number of users in the pilot program.

D - Create a set of web tests that exercise the application. Using a goal-based approach, set the process to run to 75 percent CPU utilization. When you reach that point, compare the results with the number of users in the pilot program.
